Standard SMTP on port 587 or 465. Point your existing mail library at a new host, username, and password — most migrations are a config change, not a code change.
No subusers, no enterprise tier required for isolated sending. Every plan, including the free 30-day trial, gets its own Motor Block from day one.
What you see on the pricing page is what you pay. No custom quotes, no usage tiers that only reveal themselves after a bill arrives.
Sign up, verify your sending domain, and get SMTP credentials for one project in under a minute.
Replace host/port/username/password in your existing mail library or app config — the sending code itself usually needs no changes.
Confirm delivery with a real test message, update your DNS (SPF/DKIM) for the new sending domain, then retire the old provider once you're confident.
SendGrid subusers solve a real problem — keeping one client's or project's sending reputation from affecting another's. The difference isn't the concept, it's the access tier and the setup. Subusers are gated behind SendGrid's higher-tier plans and configured through their own dashboard section; a Motor Block is what every plan starts with, created directly from the same dashboard you already use to send.
Why are people looking for a SendGrid alternative right now?
Pricing and plan changes across the transactional-email market in the last year have pushed a lot of developers to re-evaluate what they're paying for volume they may not need. That's a decision only you can make by comparing your actual sending volume against current listed pricing — we don't claim to know what your specific SendGrid bill looks like.
Do I have to rewrite my integration?
If you're using SendGrid over SMTP, no — swap the host, port, and credentials and your existing code keeps working. If you're using SendGrid's REST API specifically, you'll need to switch to Motorical's HTTP API or SMTP relay instead; the migration guide above covers the SMTP path, which is the simpler one for most setups.
What happens to my sender reputation when I switch?
Reputation is tied to your sending domain and IP history, not to your previous provider. Verify your domain's SPF and DKIM records against your new Motor Block before cutting over, and consider a gradual ramp-up if you send high volume — the same practice you'd follow moving between any two providers.
